of which the following is a specification,

reference being had therein to the accompanying drawing.

The object of the present inventlon is the provision of means forfacilitating the wrapping of a bundle without the necessity of using ast-ringtor other binder.

. Another object of this invention is the production of efficient meansfor crimping the ends of the paper while wrapping the same around thebundle, whereby the paper will be firmly held upon the bundle.

Still another object of this invention is the production of efiicientmeans for placing and holding the article to be wrapped within themachine.

With these and other objects in View, this invent-ion consiststofcertain novel constructions, combinations and arrangements of parts, aswill be hereinafterf fully described and claimed.

Fig. 4 is a rear view of the machine showingthe paper roll compartment and a paper top plan view of a portion of themachine showing the relation of the paper crimper to the supportinghead. Fig. 6 is a detail perspective of one of the paper crimpersshown'in connection with the paper guide tables. Fig. 7 is a transversesection through the. machine showing the construction of the cuttingknife. Fig. 8 is a transverse section through the paper roller andsupporting shaft showing the construction of the rod used in connectiontherewith for preventing the rotation of the shaft in one direction.Fig. 9 is a detail perspective of the connecting means for the shaftwhich supports the paper roll. Fig-1O is a perspective view of thebundle after the same has been wrapped. Fig. 11 is an enlargedlongitudinal sectional view of the wrapping frame showing thecuttingknife attached thereto. Fig. 12 is .a perspective 7 view .of aport-ion of the pair of gripping members showing the same drawn apart orin an unassembled position. Fig. 13 is a detail perspective of the papergripping controlling arms showing the means for limiting the swingingmovement of one portion upon the other. Fig. 14 is a transversesectional view through the paper gripping members showing the manner inwhich the paper is folded along the edge of the bundle.

Referring to the drawings by numerals l designates the frame which ispreferably supported *by means of integral feet 2, and this framecarries at its upper end a pair of upwardly extending arms 3. A paperroller 4: is supported between the arms 3 upon a shaft 5. The frame 1curves upwardly and connects with the longitudinally extending bars 6 ofthe frame which are supported by the top of the arms 3. A shield or hood7 is carried by the upper end of the frame 1, and has one end thereofsecured to the frame ;by means 'of a rolled edge 8 fitting under jthetransverse bar 9 which constitutes a hinge for the hood 7. The frame 1is provided uponthe top thereof with a central, transversely extendingbar 10 and near the ,lower end of the top of the frame, the same 5 isalso provided with a transversely extending bar 11. A hanger bar 12 issuspendedv from the central transverse bar 10 and this hanger barsupports a shield 13 which shield Eis adapted to cooperate with the"wraproller in section. Fig. 5 is a fragmentary f fshield 13 is braced bymeans of rods 14: Zwhich rods' depend from the transverse bar :11 andare connected to the front of the ping mechanism hereinafter described.The

shield 13. It will therefore be obvious that the front of the shield 13will be yieldably supported in view of the fact that springs 15 areplaced upon the rod 14. A pair of shafts 16 are carried by the frame 1,and

'esch of these shafts carries a drive pulley 1 The inner end of each ofthe shafts 16 is provided with a head 18. These,drive pulleys 17 aredriven by means of pulleys 19 which are carried by the shaft 5 abovedescribed. A belt 20 connects the pulleys 17 and 19. V

A plurality of. collapsible arms 21 are carried by each shaft 16 and theouter ends of these collapsiblearms are connected to the collapsiblesections 22 of the paper clamping means. There are preferably four arms21 employed, two of which are con-- I "nected to each section so thatwhen the shaft bundle before being wrapped. The paper illustrated inFig. 3. Crimpigg r is drawn around the outslde of the upper section andclamped between the adjacent edges of the collapsible sections at thepoint marked at in Fig.3. The crank 44 is then turned :}:'Of a turnthereby forming a pocket for the goods to be wrapped.

A table 23 is hinged to the frame 1,.directly below the paper roller.4,and extends artly-over the collapsible sections 22 as is members 24 arepivotally secured to the ame 1, by means of a rod 25 and the free endsof the crimping members 24 are yieldingly supported by means of springs26. These springs are preferably formed of two loopsections. Thesecrimping members 24 are substantially semicircular in cross section andas the paper from the roller 4 passes into the crimping members 24, theedges will be rolled under the table, thereby allowing the same to foldover the edges of the bundle which is being wrapped.

Theshaft 5 is provided with a pair of ratchet casings 31 which tightlygrip the aper roller 4. Ratchet pawls 32 are carried y the shaft 5 andwork in sockets 33 formed inthe shaft 5. It will be obvious that astheshaft 5 .is rotated clockwise the ratchet pawls 32 will engage theratchet casing 31 and rotate the paper roller whereend with a handlingknob 36 and at the.

other end with a stub nut and washer 37.

The knife 30 is rovided upon its upper 'edge with a lura ity ofsharpened teeth 38 and this kni e, 30 is supported upon links 39havingtheir lower ends carried byears 40 which ears are su ported upon theplate 41 of the frame 1. it will be obvious that as the knife 30 isshoved inwardly the same will rise upon the links 39 thereby pressingthe sharpened teeth 38 against the paper and severing the same from theroller. The frame 1 is rovided upon its rear with an opening 42 orallowing the bundle or goods which is desired to be wrapped to be placedwithin the pocket formed by the paper. The bundle may also be ejected orremoved from the frame through the same open ing 42.

One of the shafts 16 is provided with a coil spring-43' which springpresses against one of the heads 18. A crank 44 is also carried by thelast-mentioned shaft 16 for allowing the same to operate the machinewhen it is desired to wrap the article.

When it is desired to remove the bundle, the

crank 44 will be drawn outwardly thereby withdrawing the heads 18 and 22from the end of the bundle and allowing the bundle to be removed fromthe machine.

From the foregoing description it will be obvious that .a very simpleand eflicient de-. vice has been produced whereby the bundle may beeasily and conveniently held and the same wrap d efiicienstly afterbeing once placed witin the machine. Each of 'the pulley wheels 17 and19 are notched upon their periphery so as to allow the belt to be easilyplaced upon and removed from the wheels when it is desired to do so.

The shield 13 as stated above is suspended from the central transversebar 10 throughthe medium of the hanger bar 12 which consists of a pairof sections connected at their ends by means of a turn buckle 12.. Bythe use'of this turn buckle 12, it will be obvious that the shield 13vrolled upon the bundle '28 The wrapping of the bundle in the manner asabove stated is made possible in view of the fact that the bundlesupporting blocks firmly engage the ends of the bundle and the paper isallowed to extend upon each side of said bundle.

From the foregoing description, it will be obvious that as the pa er isfed over the bundle the ends thereo will be so crimped as to take thedesired shape after passmg 'around the bundle by first being held in engment with the crimping jaws 22.

y carefully considering Fig. 3 of the drawing, it will be obvious thatas the arms 21 are rotated to the left,-the links 21 will bestraightened in alinement with the arms 21, thereby causing thecollapsible sections to be brought tightly together at their adjoiningends. As long as the operating shaft is operated ,in the directionabovestated, the paper will be firmly grippedby the edge of the jaws asillustrated at X in Fig. 3. If, however, the shaft is rotatedin,

the opposite direction after the bundle has been once rotated, ofcourse, the arms 21 will cause the links 21' to be'released from theiralined position and again assume a collapsedposition, and allowing theadjoining edges of the gripping sections 22 to be released from eachother. I

As is illustrated in Fig. 12, the head 18 is provided with a beveledface 50 for allowing the paper to be easily removed from the head 18 andgripping members 22 when the head 18 is drawn from the edge of the paperwrapped around the bundle. This feature is clearly illustrated in Fig.14. The paper gripping members 22 are supported by arms 2]. aspreviously described which arms are integrally connected together. Thearms 21 are keyed to the axle 52 formed upon the shaft 16. The outerface of the arms are engaged by means of a roughened washer 54, whichwasher is in turn engaged by means of a nut 55 having a milled orroughened face engaging the washer whereby the nut will firmly hold themember 51 in its proper place upon the stub shaft 52. The arms 21 areprovided near their outer ends with angular, laterally extending members56 which are adapted to engage the sides of the links 21' for limitingthe pivotal movement of said arms in one direct-ion. Each of thelinks'21 is also provided with a depending finger 57 which is alsoadapted to engage the angle members 56 carried by the arms 21 forlimiting the pivotal movement of the link 21 in the opposite direction.Of

course, it should be understood that when the paper is cut the cut edgeis still a dis-- tance from the bundle and the crank 44 is rotated untiltheend of the paper has reached the bundle. The free end of the papercarried by the roller follows the cut edge of the paper wrapped aroundthe bundle and then the operation of the crank in discontinued andoperated in the opposite direction, thereby releasing the edge of thepaper from the paper grippersand allowingthe bundle to be removed fromthe machine, and the edge of the paper to be released from the grippers.Of course, the edge of the paper for receiving a new bundle may also beattached as previously described.

semicircular guards 29 are carried by each side of the frame 1 and areadapted to engage the edge of the paper carried by the roller forguiding the same directly to the paper crimpers. A stationary table 29is carried by the lower edge of the semicircular guards 29, and thisstationary table is adapted to protect the paper as the same is firstcut by the knife 30. The inner ends of the semicircular guards 29 aremuch lower than their outer ends so as to guide the paper directly nearthe knife, and facilitate the cutting thereof. The feet 2 of the body 1are provided with apertures 58 through &

holding the wrapping machine upon a support.
